Convectional rainfall
Rainfall in mountain areas is called: Orographic rainfall.
Deserts receive little rainfall.
Semiarid climates
The difference lies in what causes the rainfall to occur. In convectional rainfall, the sun heats the earth and the heat causes moisture from soil, plants and open water bodies to evaporate. This moisture is carried upwards through convective air currents until it reaches a certain altitude. At that point, where the air is cooler, it condenses and creates water droplets (rain). This usually occurs in the afternoon on warm summer days. Frontal rainfall occurs because of the movement of the fronts of two air masses. When a cold front is moving over a mass of warm air, it causes the warm moist air to rise. In this case, rain occurs ahead of the cold front. When a warm front is moving over a mass of cold air, the warm moist air is forced upward, and the rain occurs over or behind the front. Finally, relief rainfall is caused by changes in topography. Moist warm air can be forced upward by mountains, for example, which causes the moisture to condense into rain. This type of rainfall occurs on the side of the mountain away from the wind direction.

The retreating rainfall monsoon occurs when the temperature on land is significantly warmer or cooler than the temperature of the ocean.
Tropical climate. Rainfall occurs all the year because of the domination of low pressure.
if we grow trees ,rainfall occurs
It depends on what city you live in. In London or Seattle there might be more rainfall, but most rainfall usually occurs in the spring.
Conventional rainfall occurs because the ground is heated in early morning.so it occurs in early afternoon.Relief rainfall occur only when the South East Trade Wind blows with full force and the South East Trade Wind can blows at any time of the day
the amount of rainfall that occurs in a set time
The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
